No doubt, some aspects of these conclusions will change over time as more examples are collected. For anyone interested in reviewing the data upon which, in part, these observations were based, visit Watch Data - Early advertisements also support these conclusions and can be found at - Dating a Bulova watch becomes quite a bit easier beginning with models manufactured in At that time, Bulova started using with regularity standard date codes on the movement.

Additionally, in many instances, the case serial number on these later models can be used as a date reference. For models manufactured beforethere is typically no date code on the case itself though there are exceptions seen in the later s.

However, as stated, the case serial number can often be used to date the case, while the movement code indicates the date the movement was made. Thus, most watches have two manufacture dates, providing a useful tool for determining whether a particular case and its movement were originally intended to be paired.

Instead, the appropriate decade must be determined by examining the style of the watch in light of the styles of each decade. Below is an example of a watch, where the year of manufacture has been determined using both the symbol on the movement and the matching serial number, along with an examination of the watch's characteristics.

Important factors in identifying the proper decade of the watch's manufacture based on it styling include the size and shape of the case, engraving placement and patterns, dial and hand designs, and movement calibers. A very good place to study styles by decade is right here on Watchophilia. The large collection is organized by decade, and all watches for a given decade can be viewed together on one page, making it easy to scan the page and note the styles used during that time period.

Becoming familiar with other examples and with the available advertisements will also help determine when elements, such as dials, hands, and straps, are not original to the watch and should not be considered when determining the date.

Before we move on to the s, we need to consider exceptions to the serial number method of dating a Bulova watch.

Below are examples of this style of date code on the movement and case. Ideally, the date of the movement will match the date of the case. Occasionally, however, that is not the case. In those circumstances, I subscribe to the "latest date wins" theory only when the case and movement are dated within one year of each other.

If more than one year separates the movement and the case, for me, the case date rules. The reason for that limitation is that movements can, and often are, replaced when the original one breaks.

So, it has problems being identified, both because it is very early and because it is solid gold see above for problems with serial numbers and solid gold cases as well as early movements with no date code.
